5G promises to enable a variety of new services, ranging from high-speed, high-capacity broadband access to ultra reliable low-latency communications to massive machine-type communications. To deliver on these promises, the wireless network must change, including the devices, the radio interface, the radio access network (RAN), and the core network. Part I of this self-paced course offers a high-level technical overview of 5G NR (New Radio) air interface – its features, the use of low-mid-high band spectrum, the reuse of the principles of OFDM/OFDMA, and the use of massive antennas for beamforming and MIMO. Part II covers the flexible numerologies, channels and frame/slot structure, and steps through the life of a 5G UE. Part II concludes with how the technologies and standards converge to meet the performance goals set for 5G.

This course is designed for a broad audience of wireless network engineers. This includes those in RF, RAN planning, engineering, operations, troubleshooting and support groups.

After completing this course, the student will be able to:
■ List the performance goals of the 5G network
■ Compare the different 5G frequency spectrums and their characteristics
■ Describe MIMO and the beamforming techniques used in 5G
■ List the key features of the 5G NR air interface
■ Sketch the flexible frame and slot structure of 5G NR
